Hi there, after 2 days stuck under the bloody thing all new TX box in, all working treat. Now occasionally the 4x4 light says on after starting, turn the car off turn it on again straight out. Its not the box, i can assure you, as I did 5000 miles on it in the calibra it came out of, and as once the light is off, it never comes on again until you turn car off, and then turb ign back on.
I would say 90% of the time it goes out 10% it stay on.
woosh test only gives about 8/9 wooshes... is the accumulator knackered????
